TikZ 样式，带有两个贯穿列表的参数

Question

我如何定义一种样式，让两个参数在列表中采用成对的值？在我的例子中，样式是

\tikzset{
    loop/.style 2 args={decoration={markings,
        mark=at position {#1} with {\arrow{>},
        \node[anchor=\pgfdecoratedangle-90] {$p_{#2}$};}},
        postaction={decorate}}
}

Answer 1

啊哈，我刚刚明白了。这个有效：

\documentclass[tikz]{standalone}

\usetikzlibrary{decorations.markings}

\tikzset{
    loop/.style 2 args={thick,decoration={markings,
        mark=at position {0.0625*#1} with {\arrow{>},
        \node[anchor=\pgfdecoratedangle-90,font=\footnotesize] {$p_{#2}$};}},
        postaction={decorate}}
}

\begin{document}
\begin{tikzpicture}

    \draw[loop/.list={{1}{6},{3}{1},{5}{2},{7}{3},{10}{4},{14}{5}}] (0,0) circle (1);

\end{tikzpicture}
\end{document}
